THlLL-COUPLING.

ilPEfiIl-ICATION forming part of Letters Patent Ila 338,067, dated March 16 1886.

Application filed November-2,1885. Serial No. 181,626. (No model.)

To (LZZ whom it may concern:

Be it known that I, LUTHER D. HASKELL, J r., of Beverly, in the county of Essex, State of Massachusetts, haveinvented acerta-in new and useful Improvement in Thin-Couplings, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertaius to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a front elevation of my improved coupling; Fig. 2, a vertical transverse section of the same; Fig. 3, views of the cushion-rod detached; Fig. 4, a diagram of, the cushionbed detached; Fig. 5, a diagram of the cushion detached; Fig. 6, a diagram of the cushioncap detached; Fig. 7, a view of the nut for the cushion-rod detached.

Likeletters ofreference indicate correspond- ,ing parts in the different figures of the d rawings.

My invention relates more especially to means for preventing the thill from rattling; and it consistsin a novel construction and arrangement of the parts, as hereinafter more fully set forth and claimed, by which a more desirable and effective device of this character is produced than is now in ordinary use.

The nature and operation of the improvement will be readily understood by all conversant with such matters from the following explanation:

In the drawings, A represents the clip, which is attached to theaXle and bolster in the usual manner by bolts and nuts B. Projecting from the front side of the body of the clip there are two arms, 0, arranged in parallelism, in which the thill-iron D is j ournaled by the screw-bolt E. The thill-iron is bifurcated or provided with two arms, H, through which the bolt E passes, said bolt being held in position in the arms 0 H by a nut, J. A rod, K, provided with the head at ,and having its outer end threaded, as shown at :r, is suspended on the bolt E, between the arms H of the iron D, said bolt passing through a hole, f, in the head of the rod. Disposed on said rod there is a cushion-bed, L, a cushion or elastic pad, M, a cushion-cap, N, and nut O, the rod passing through suitable holes in these parts. The cushionbed L is curved or concared on its upper side, as shown at o, to receive the arms H of the thill-iron D, and provided with asquare socket, 2, to receive the upper end of the cushion M, which is also square in cross-section. The cushion-cap N is provided with a square socket, t, to receive the square lower end of the cushion. and on its outer face with a series of projections or teeth, 1*. The nut O is pro vided with two beveled projections, 1), adapted to engage theteeth 'r and ride over them when the nut is forcibly turned onto the rod K to compress the cushion M. The projections b and teeth 9' form a lock to prevent the not from accidentally unscrewing from the rod K. The cushion M being square and fitted into the square sockets of its bed Land cap N,thereby prevents said cap from turning as the nut is screwed onto the rod, and enables the projections 1) to ride over the teeth 9', it being understood that as the projections pass said teeth the expansive action of the cushion will cause them to fall into the spaces between the teeth, and thus lock the nut in any position in which it may be left when the parts L M N O are in forcible contact.

In the use of my improvement, when the nut O is turned onto the rod K and the cushion M compressed. the bed L will be forced against the arms H, and the thill .prevented from rattling in a manner which will be readily obvious without a more explicit description.

It will be obvious that any required degree of tension may be applied to the cushion by means of the nut O; also,that the nut J may be furnished with a lock, if desired.

Having thus explained my invention, what I claim is 1. Athill-coupling comprising an axle-clip provided with two parallel perforated ears, a thill-iron having two parallel perforated arms adapted to fit between said ears, a bolt for connecting said parts, a downwardly-extending rod having a perforated head, through which the bolt also passes, and a screw-threaded lower end, a cushion-bed disposed on said rod and adapted to bear against said ears, said bed being provided with a square socket on its opposite face, a cushion-cap, also disposed on said rod,and provided on its inner face with a square socket and on its outer face with a series of teeth, asquare cushion between said bed and cap adapted to fit within said sockets, and a nut on the screw-threaded end of said rod, said nut being provided with projections adapted to engage said teeth.

2. A thin-coupling comprising an axle-clip provided with two parallel perforated ears, a

thili-viron having two parallel perforated arms adapted to fit between said ears, a bolt for connecting said parts, a downwardly-extending rod having a perforated head, through which said bolt also passes, and ascreW-threaded lower end, a cushion-bed disposed on said rod and adapted to bear against said ears, said bed being provided with a square socket on its opposite face, a cushion-cap also disposed on said rod and provided on its inner face with a square socket and on its outer face with a series-of teeth, a square cushion between said bed and cap adapted to fit within said sockets, and a nut on the screw-threaded end of said rod, said nut being provided with beveled projections adapted to engage said teeth.
